    This paper deals with discovering M2M overlay entities in Machine-to-Machine (M2M) service networks. The eXtensible Messaging and Presence Protocol (XMPP) is used as a basic building block for the M2M communication. XMPP does not offer mechanisms for discovering unknown entities from unknown contacts, and this paper's goal is to provide a protocol enabling this. The presented protocol does this by using asynchronous remote procedure calls (RPCs), unicast messages and friend-to-friend type of communication. The paper proposes new XMPP subscription statuses to enable exchange of roster items in the M2M overlay entity discovery protocol without compromising privacy, and presents the protocol for discovering unknown M2M overlay entities from unknown M2M overlay entities.
